Daily Ceramics inoshandiswa zvakanyanya muhupenyu hwezuva nezuva, senge tableware, seti yeti, seti yekofi, seti yewaini, nezvimwe. Ndidzo zvigadzirwa zveceramic izvo vanhu vanosangana nazvo zvakanyanya uye vanonyanya kujaira. Kuti uvandudze "kuonekwa kwekukosha" kwezvigadzirwa zveceramic zvezuva nezuva, pamusoro pezvigadzirwa zvinowanzoshongedzwa nemapepa emaruva e-ceramic uye anopiswa pakupisa kukuru. Inogona kukamurwa kuita overglaze color, underglaze color, uye underglaze color zvigadzirwa. Nekuda kwekuti mapepa emaruva mazhinji ekushongedza ane simbi inorema, pane njodzi yekuparara kwesimbi inorema panguva yekusangana nechikafu.
Unhu uye njodzi dzekuchengetedza
▲Njodzi
Mukugadzirwa kweceramic tableware, simbi inorema senge lead uye cadmium inogona kunge iripo mune glaze uye yekushongedza mapatani. Kana yakashandiswa iine chikafu, kunyanya chikafu chine acid, inogona kukonzera lead uye cadmium kunyungudika muchikafu uye kupinda mumuviri wemunhu. Lead necadmium zvinhu zvinorema zvesimbi zvinopinda muropa zviri nyore uye hazvibudisi nyore kubva mumuviri. Kushandiswa kwenguva refu kwechikafu chine lead uye cadmium kunogona kukanganisa immune system yemunhu, zvichikonzera kuitika kwezvirwere zvakasiyana.
Zviratidzo zvikuru zvecadmium poisoning ndeye arteriosclerosis, renal atrophy, nephritis, etc. Mukuwedzera, cadmium yakawanikwa iine carcinogenic uye teratogenic madhara. Cadmium inogonawo kukonzera hypertension uye kukonzera zvirwere zvemwoyo uye cerebrovascular; Kukuvadzwa kwemapfupa, chiropa neitsvo, uye zvinogona kukonzera kutadza kwetsvo.
Lead imhando ine muchetura weheavy metal pollution, iyo inogona kutungamira kune isingaperi chepfu mushure mekubatwa nemuviri wemunhu. Vana vanoratidzwa kutungamirira kwenguva yakareba vanowanzoita zvishoma nezvishoma uye kusaona. Mutobvu uchipinda mumuviri wemunhu unogona kukuvadza zvakananga maseru ehuropi, kunyanya sisitimu yetsinga dzevacheche, izvo zvinogona kukonzeresa kuremara kwehungwaru muvana. Mukuwedzera, kune ngozi yekenza uye kuchinja.
▲Standard zvinodiwa
Tichifunga kuti simbi inorema yakawandisa inogona kukuvadza muviri wemunhu, Chinese zviyero GB 4806.4-2016 "National Food Safety Standard Ceramic Products", FDA/ORACPG 7117.06 "Cadmium Pollution of Imported and Domestic Household Ceramics (Porcelain)", uye FDA/ORACPG 7117.07 "Lead Kusvibiswa Kwekune dzimwe nyika uye Mumba Household Ceramics (Porcelain)” The EU Directive 84/500/EEC “Council Directive on the Compliance and Performance Standards for Ongororo Nzira dzeCeramic Products muKusangana neChikafu” uye 2005/31/EC “Council Directive 84/500/EEC on Kudzokororwa Kwemafambiro uye Maitiro Ekuita kweOngororo Nzira dze Ceramic Zvigadzirwa Mukubatana neChikafu ”inonongedza miganho yekuparara kwe lead uye cadmium. The California Prop.65-2002 California Drinking Water Safety and Toxic Substances Enforcement Act inoisazve zvirambidzo pakuburitswa kwemutobvu necadmium, kusanganisira zvinodikanwa zvemukati, muromo, uye muviri wechigadzirwa; Iyo yeGerman LFGB 30&31 "Chikafu, Fodya Zvigadzirwa, Zvizoro, uye Zvimwe Zvemazuva ese Zvinodiwa Management Mutemo" yakawedzera zvirambidzo pakuparara kwecobalt pahwaro hwekutungamira uye kuparara kwecadmium.
Mazano ekutenga nekushandisa
(1) Nyatsotarisa kutaridzika kwetafura kune chero kukuvadzwa, mabhubhu, mavara, nezvimwewo (2) Edza kusarudza zvigadzirwa zvisina ruvara rwekushongedza mukati nekunze kwemiromo, kunyanya ceramic tableware nekushongedza kwemukati, iyo inounza hunokosha hutsika uye njodzi dzekuchengetedza Edza kutenga zvigadzirwa zvinoenderana kubva muzvitoro zviri pamutemo uye dzivirira kutenga zvigadzirwa zvine mavara emaruva emapepa ekushongedza pamapuratifomu e-commerce. (4) Dzivisa kuchengetwa kwenguva refu kwechikafu chine acid uye doro uchishandisa ceramic tableware ine yemukati yekushongedza mifananidzo. Iyo yakareba nguva yekuchengetedza, inowedzera tembiricha yekudya, uye zviri nyore kunyungudutsa simbi inorema. Kunyanya kunyungudika kwe lead uye cadmium kunogona kukonzera chepfu mhedzisiro uye kukuvadza hutano.
